HTML Entity Encoder & Decoder - Free

How the HTML Entity Encoder Works

1. 01Paste your text or HTML into the input field
2. 02Choose Encode to convert special characters to HTML entities, or Decode to reverse it
3. 03Characters like <, >, &, and " are converted to &lt;, &gt;, &amp;, and &quot;
4. 04Copy the result for safe use in your HTML documents

Why HTML Entity Encoding Matters

HTML entity encoding converts special characters into their safe HTML equivalents. This is critical for preventing XSS (cross-site scripting) attacks - unencoded user input can be interpreted as executable HTML or JavaScript. Always encode user-generated content before inserting it into HTML. The five characters that must always be encoded are: & (&amp;), < (&lt;), > (&gt;), " (&quot;), and ' (&#39;).

When to Use the HTML Entity Encoder

Use this tool whenever you need to safely display special characters in HTML, or when you encounter encoded entities that need to be converted back to readable text. It is critical for preventing XSS attacks when inserting user-generated content into HTML, encoding code examples for blog posts, and preparing text for HTML email templates.

Common Use Cases

• ·Encoding user input before inserting it into HTML to prevent XSS (cross-site scripting) attacks
• ·Preparing code snippets with angle brackets and ampersands for blog posts and documentation
• ·Encoding special characters for HTML email templates that need to render correctly across email clients → Meta Tag Generator
• ·Decoding HTML entities in scraped web content to extract clean readable text

Expert Tips

• ✻When in doubt, encode everything - browsers decode entities automatically during rendering, so over-encoding is safe
• ✻For code blocks in HTML, encode both < and > to prevent the browser from interpreting tags: use &lt;div&gt; instead of <div>
• ✻URL encoding (percent-encoding) is different from HTML entity encoding - use the right encoding for the right context
